@dream2reality Your son should be a NMSF anywhere.
OP, there’s no way she got a full ride to Harvard just with her PSAT score. That’s BS. However, there are schools you can get full rides or full tuition+ too. Wichita State University in Kansas gives a full ride to National Merit Finalists - if you qualify for Semifinalist (which is what people are saying you likely will), you have to fill out an application that includes your grades, ECs, a recommendation from someone like a guidance counselor or teacher, and an essay. You also have to take the SAT, score above 1960, and send that score to NMSC. As long as your grades aren’t too low (NMSC doesn’t like Cs) you should make Finalist. University of Oklahoma and University of Alabama offer large, though not full ride, scholarships for NMFs and have large programs for them. Congrats on your high score! If you play your cards right, you could have some great opportunities for college!
